If your car's windshield is damaged, a few methods can be used to fix chips and cracks in the glass. The method chosen will depend on the size and location of the damage, as well as the type of windshield. 

So you have a clear understanding of how your windshield can be fixed, here are the various methods used in professional automotive glass repairs:

Resin Injection: The most common method of windshield repair is resin injection. As the name implies, resin injection repairs involve injecting a special resin into the damaged area. The resin is cured using UV light, helping to bond the resin to the glass and strengthen the repair. The resin injection process is cost-effective, quick, and simple, making it practical for minor chips and cracks.

Bridge Method: The bridge method is a type of resin injection that utilizes a specialized tool called a bridge. The bridge is placed over the damaged area, and a small amount of resin is injected under pressure. The bridge helps distribute the resin evenly across the damaged area, filling the crack and bonding the glass. This method is more time-consuming than other methods but is a more practical option for larger windshield chips and cracks.

Injection and Curing: A more advanced resin injection glass repair method is called 'injection and curing.' This method is typically used for larger chips and cracks and injects a special UV-cured resin into the damaged area. Because this method is more time-consuming than other methods, it is often used for larger chips and cracks that can't be repaired with other methods. As you can imagine, injection and curing are more expensive repair options.

Vacuum Injection: Another method of windshield repair is vacuum injection. This method is used for larger chips and cracks and involves injecting a special resin into the damaged area of the windshield using a vacuum. The vacuum helps to pull the resin into the crack, which helps to fill the damage and strengthen the repair. Vacuum injection is a fast process and is often a more cost-effective option than windshield replacement for larger chips and cracks.

Repair Is Impossible: In some cases, replacing a windshield is necessary because its damage cannot be repaired. Typically, this happens when the chip or crack is too large or when the damage is in the driver's line of sight. In these cases, the windshield will need to be replaced. This process will take several hours, and it can be quite expensive. However, your car insurance may cover some of the cost.
